An overview is presented of the antenna research carried out by the Di
rectorate of Antennas and Integrated Electronics (DAIE) of the Communi
cations Research Centre (CRC). The antenna research within the DAIE ca
n be categorized into two groups: antenna-hardware development and ele
ctromagnetic-software development. Recent research in antenna hardware
has been focused on printed multi-layer arrays, dielectric-resonator
antennas, ferrite antennas, active-circuit integration, and low-loss f
eed networks. Research in electromagnetic software includes the develo
pment of three-dimensional transmission-line-matrix (TLM) code, and th
e application of cellular automata (CA) techniques for the analysis an
d modeling of antennas, microwave circuits, and general electromagneti
c phenomena, such as scattering. This article concentrates on the ante
nna-hardware research and development within the DAIE.
